You are not getting the point.
Something has value if it is perceived as having value. Money itself is just a piece of paper, like bitcoin (or any crypto coin) is just a 0 and a 1 on an electronic device.
Actually, BTC is more valuable than money because money can be printed forever (=> inflation) without a limit. BTC has a finite supply which will be reached around 2100, exactly like gold.
Also, you say that BTC is useless, but here you are buying weed from the comfort of your house using... Bitcoin!
Also, this is not the first time BTC falls down so strong, in 2024 it will be the next halving (one block mined will reward 1/2 btcs of the actual block) thus the value will again skyrocket.
I'm not saying that is not risky, it is risky if you do not understand in what you are investing (and this does apply to all types of investments).
Also, you should focus more on the technology behind BTC, blockchain, which a lot of business started to use for many purposes.
You should always embrace the future, not fight against it.
